SPECIFICATION forming part of Letters Patent No. 652,646, dated .Tune26,.'1. 900. Application filed January 2, reco. serai M109. (No model.)

To all whom, it may concern,.-

Be it known that I, JOHN F. SCHENCK, a citizen ofthe United States,residing at Lawndale, in the county of Cleveland and State of NorthCarolina, have invented new and useful Improvements in Thread-WindingMachines, of which the following is a specification.

This invention relates to the thread-winding machine for forming ballsor cops by winding cord or thread in recrossing spirals runningalternately in opposite directions upon and from end to end of acop-tube carried by a rotary winding-spindle, as described. and shown inLetters Patent No. 638,360, issued to me December 5, 1899.

The chief objects of my present invention y are to generally improve theformer threadwinding machine; to simplify the machine by avoiding theemployment of an oscillatory thread-guide carrier pivotally mountedconcentric with the axis of the cam-shaft which reciprocates thethread-guides; to provide fa new and improved thread-winding machinewherein the thread-guide carrier is immovable during the Windingoperation and the frame which carries the rotary winding-spindle recedesin a horizontal path, while preserving operative gear connection of thespindle with the shaft which drives it; to provide novel, simple, andefficient means for automatically stopping the winding-spindle Vduringits receding motion from the threadguide when the ball or cop hasreachedthe required diameter or is of the desiredsize, and to provide athread-winding machine having a Winding-spindle which recedes during thewinding operation with novel means whereby either cylindrical orconoidal-shaped balls or cops may be wound.

To accomplish all these objects my invention involves the features ofconstruction, the combination or arrangement of parts, and theprinciples of operation hereinafter described and claimed, referencebeing made to the accompanying drawings, in which-` y Figure luis atopplan view of sufficient of the thread-winding machine to enable myinvention to be clearly understood, the spindle being moved back fromthe threadguide. Fig. L is a rear side elevation, partly in section.Fig. 3 is a vertical sectional view taken 4on the line 3 3, Fig. 1, thespindle being `5 is a detail sectional elevation showing the eccentricin which the winding-spindle rotates and a portion of the gearing andsupportiugdevices by which the Winding-spindle is driven from the maindriving-shaft. Fig. 6 is a detail perspective View of the lockingdog andits' adjustable tripping device by which the clutch of thewinding-spindle is automatically disengaged to stop the winding-spindlewhen the ball or cop reaches the required diameter or is of the desiredsize. Fig. 7 is a detail view of a portion of the differential orepicycle train of gearing by which motion is transmitted to thecam-shaft from the main driving-shaft; and Fig. Sis a detaillongitudinal sectional view through the Winding-spindle, its bearings,and the sliding carriage. A

In order to enable those skilled in the art to make and use myinvention, I will now describe the salue in detail, referring to thedrawings, wherein the numeral 5 indicates a main frame of anyconstruction for the purpose in hand, provided at proper points withshaftbearings, in which is mounted a continuous longitudinal shaft 6,provided with a cam 7 for reciprocating the thread-guide 8. As shown,the cam is constructed with a cam-groove 9, into which projects aroller-stud 10, Fig. 2, on the lower portion of the thread-guide S.

The main frame is provided with perpendicular semicircular plates orsupports 12, connected at their top portions by a fiat horizontal plate13, on which is mounted the thread-guide carrier 14E, having arectilinear guideway in its rear side by which. the threadguide S isaccurately guided in its reciprocating motions. Thethread-guide carrieris immovable during the Winding operation in contradistinction to beingpivotally mounted to oscillate in the arc of a circle, as inmy patenthereinbefore mentioned; but the carrier 14 is made adjustable on theplate or support 13, as will be hereinafter described in detail, for thepurpose of winding either cylindrical or conoidal -shaped balls or cops.The main frame is also provided with suitable bearings IOO .section 37.

in which acontinuous main driving-shaft 15 is mounted. This shaft isparallel with the camshaft 6 and may be operated in any suitablemanner3butashere shownitisprovided atone end with fast and loose pulleys16 and 17, Fig. 1, for use in connection with a belt actuated byanengine ormotor. The driving and cam shafts may extend any desiredlength, according to the length of the machine and the number ofwinding-spindles to be operated in a single machine; but in the drawingsI have only illustrated a single winding-spindle and the mechanismnecessaryin connection therewith for winding a ball or cop.

The main frame is provided with uprights or standards 18 and 19,supporting a cylindrical guide-rod 2O at their upper ends, and saidframe is also provided with similar uprights 0r standards 21 and22,supporting a horizontal guide-bar 23 at their upper ends. The rod 2Oand bar 23 are thus held in an elevated position and extend transverselyof the machine to constitute supporting-guides for atransversely-slidable carriage or frame 24, which carries the rotarywinding-spindle 25. This spindle extends through a bearing 26,mounted onone end of the carriage or frame 24, and into a bearing 27 on theopposite end of said carriage or frame.

An oscillatory or swing arm 28, journaled on the driving-shaft 15, (bestseen in Figs. 3 and 5,) is pivotally connected at its upper end, as

at 29, with a lever-arm 30 on a collar, ring, or eccentric-strap 31,containing a disk 32, through which the winding-spindle 25 eccentricallypasses, whereby the disk 32 becomes an eccentric, susceptible of beingturned in the collar or ring 31 and to be rigidly locked to the collarthrough the medium of aset-screw 33, for a purpose which willhereinafter appear.

At one side of the collar or ring 31 the Winding-spindle is providedwith a collar 34, rigidly secured to the spindle by a set-bolt 35, andon the spindle at one side of the collar 34 is loosely7 mounted a pinion36, to which is attached one section 37 of a clutch, the other section38 of this clutch being adapted to slide longitudinally on the spindle,but compelled to rotate with the latter in any suitable manner--as, forexample, by connecting the clutch-section 38 with the winding-spindle bya feather or spline, as will be obvious. The clutch-section 38 isprovided with an annularly-grooved hub 39, into which projects a pin 40on a clutch-lever 41, pivoted centrally between its extremities to thecarriage or frame 24 through the medium of a pivot pin or bolt 42. Theclutch-lever 41 is acted upon Vby a suitable spring 43 to swing it inthe direction which will throw the clutchsection 38 out of engagementwith the clutch- The clutchlever is operated manually to engagetheclutch-sections, and it is automatically locked to hold theclutchsections in engagement through the medium of the followingdeviceszThe rear .t t i 652,646

end of the clutch-lever is provided with a lug 44, which engages theshouldered end 45 of a pivoted dog 46 when the clutchlever is manuallyoperated to throw the clutch-section 38 into engagement with theclutch-section 37. The dog 46 is pivoted centrally between its ends tothe carriage orframe 24, and its shouldered end 45 is thrown into thepath of the lug 44 through the medium of a suitable spring 47. The dog46 carries a latch 48, pivoted, as at 49, Fig. 6, so that the latch canswing vertically. This latch bears squarely against the rear side of thedog 46, and its outer free extremity 50 is adapted to strike atrip-block 5l .when the carriage 24 is slid horizontally toward the rearside of the machine, thereby disengaging its shouldered end 45 from thelug 44, which releases the clutch-lever, so that the latter is instantlyswung by the action of the spring 43 in the proper direction todisengage the clutch-sections, whereby the rotary motion of thewinding-spindle will be instantly stopped. The. winding-spindle isrotated by thel mechanism hereinafter explained.

On first starting to wind a cop the carriage is moved backward to placethe windingspindle at the greatest distance from the thread-guide forthe beginning of the winding operation for reasons appearing later on.The clutch-lever 41 is then manually operated to engage theclutch-sections and cause the lug 44 of the clutch-lever to engage andbe locked by the shouldered end 45 of the dog 46, after which thecarriage may be drawn forward to its operative position. As the carriageor frame 24 is drawn forward or toward the front ofthe machine the latch48 will ride up the inclined upper end 52 of the trip-block 51 to enablethe latch and dog to pass by this trip-block.

The trip-block 51 is mounted on a screwthreaded shaft 53, arranged inbearings on one side of the guide-bar 23. The screwthreaded shaft isprovided with a suitable handle or finger-piece 54, by which it may berotated to adjust the trip-block 51 forward or backward, and thus varythe time at which the dog 46 is actuated to release the clutchlever anddisengage the clutch-section for stopping the winding-spindle. Obviouslythe trip-block can be set in any desired position to disengage theclutch-sections and stop the winding-spindle at a predetermined time forwinding balls or cops of any desired diameter or size.

The pinion 36, loosely mounted on the winding-spindle 25, meshes with anintermediate traveling gear-wheel 55, engaging a pinion 56, which isconstantly engaged with and is adapted to travel partially around aspurgear 57, secured to the main driving-shaft 15. The gear-wheel 55 isjournaled on a bearing formed on the swing-arm 28, and the pinion 56 isjournaled on an arm 58, adjii'stably secured to the swing-arm 28 by aset-bolt 59, passing through a slot 60 in the arm 58 into IIO theswing-arm 28. (Best seen in Fig. 5.) The rotation of the maindriving-shaft 15 transmits rapid motion to the pinion 36 on thewinding-spindle 25 through the medium of the spur-gear 57, pinion 56,and gear 55, and the swing-arm v28, in connection with the collar orring 3l, adapted to slightly turn with the eccentric 32 on the spindle25, enables the slidin g carriage or frame 24 to move back and forth ina horizontal plane, while preserving the operative gear connectionbetween the winding-spindle carried by such sliding carriage or frameand the spur-gear 57 on the main driving-shaft l5. In this manner thewinding-spindle as the ball or cop grows or increases in diameter orsize is forced to recede in a rectilinear pathway in a horizontal planeaway from the reciprocating threadguide and stationary threadguidecarrier; but at the same time during the entire winding operation thepinion on the winding-spindle will remain in gear with the drivingspurgear on the drivingshaft.

The purpose of the eccentric is to enable pinions of varying diameter,like pinion 36, to be placed upon the winding-spindle for the purpose ofincreasingor diminishing the speed of the spindle, and thereby varyingthe distance between the spirals of the thread wound during the windingoperation. If it is desired to place a larger pinion, similar to pinion36, on the Windingspindle 25, the eccentric is turned in the collar orring 3l to increase the distance between the axis of the winding-spindleand the axis of the pivot 29, thus providing the space necessary toapply the larger pinion in operative connection with the winding-spindleand the gear-wheel 55.

' The substituted larger pinion will diminish the speed of thewinding-spindle, and consequently the spirals or threads will be Widerapart, and, conversely, if a smaller pinion be substituted for thepinion 36 the speed of the Winding-spindle will be increased, thusplacing the spirals of thread closer together. As the winding-spindleand its carriage or frame bodily move back and forth in a horizontalplane the swingarm 28 rocks on the driving-` shaft 15, and the collar orring 31 and eccentric 32 slightly oscillate on the winding-spindle, sothat under all circumstances or conditions the winding-spindle ismaintained in correct operative gear connection with the spur-gear 57 onthe driving-shaft. W'hen the swing-arm rocks on the driving-shaft, thepinion 56, carried by the arm 58, travels partially around thecircumference of the spurgear 57.

The main driving-shaft 15 is provided with a pinion 61, Vengaging apinion 62, loosely mounted on the cam-shaft Gand connected bydifferential or epicycle gearing with the worm 63, the same as in myLetters Patent hereinbefore mentioned, in such manner that byinterchangeable worm-gears, as at 64, engaging the worm 63 on thedriving-shaft the speed of rotation of the cam-shaft may be varied forvarying the speed of the reciprocat ing thread-guide to suit theconditions required where fine or coarse thread is to be Wound intoballs or cops. As in the former patent, a change in the speed of thecam-shaft correspondingly changes the speed of the threadfguide. If afine thread is being wound, the speed of the thread guide should beslightly varied to cause it to move less rapidly, and if a coarse threadis being wound the variation in the speed of the thread-guide should besuch as to cause it to move more rapidly.

The wornrgear 6i is xed to an inclined shaft 66, mounted in bearings ina suitable adjustable frame 67 and carryingabevel gearwheel 68, meshingwith a larger bevel-gear 69, having an attached pinion 70 meshing into acomparatively-large differential gear 7l, connected by the bevel-gears72, 73, 74, and 75, Fig. 1, with the spur-gear 62. The adjustable frame67, carrying the shaft 66, renders it possible to substitute a larger orsmaller Worm-Wheel for the worm-Wheel 64. This entire differential orepicycle gear mechanism is constructed and operates substantially thesame as in my patent before referred to and enables the speed ofrotation of the cam-shaft to be varied. Further description of thismechanism is therefore not considered essential herein. Y

A cable or cord 76, secured at one end to the carriage or frame 24,passing over a guidepulley 77 and supporting a Weight 78, Fig. 3,constantly tends to pull the sliding carriage or frame forward or towardthe reciprocating thread-guide to hold the ball or cop being Wound inclose contact with the thread-guide for the purpose of regularly anduniformly winding the balls or cops. As the ball or cop grows orincreases in diameter or size the winding-spindle and the slidingcarriage or frame are caused to recede or remove in a direction awayfrom the thread-guide, and When the ball or cop has reached the desireddiameter or size the trip-block actuates the locking dog of theclutch-lever, thus releasing the latter and unclutching theclutclrsections, so that the windingspindle instantly ceases to rotate.

The thread-carrier le is adjustable to different angles relative to thelongitudinal axis of the winding-spindle through the medium of bolts 79and 80, Figs. '1 and 3, for the purpose of causing the thread-guide totravel in a plane parallel with the axis of the Windingspindle or at anyrequired angle with relation thereto in order to wind either cylindricalor conoidal balls or cops. The bolt 80'constitutes a fulcrum or pivot onwhich the threadguide carrier 14 can be swung horizontally. The bolt 79passes through a segmental slot 81 in the carrier 14 at a point in frontof the fulcruin or pivot bolt 8O and screws into the loosening the bolt7 9 the thread-guide carrier IOC IIO

can be adjusted or turned on the bolt 8O as a fulcrum or pivot to therequired position and then be rigidly fixed by tightening the bolt 79 inits screw-threaded oriice in the plate 13.

The cop-tube may be secured to the winding-spindle in any suitablemanner-as, for instance, by a friction-spring 82, a portion of which isshown in Fig. 8 and Which is constructed the same as in my formerpatent. The thread to be Wound is led to the cop-tube on thewinding-spindle through any suitable tension device-as, for example,that indicated at 83. f

The motion of the Winding-spindle and its sliding carriage or frame in arectilinear path not only simplifies the gear connections with thedriving-shaft, but enables me to employ a comparatively-shortthread-guide and to constantly maintain the eye of the threadguide in aplane coincident With a horizontal line drawn through the centers ofsuch eye and the- Winding-spindle, thereby obtaining perfect Windingunder all conditions, particularly at the ends of the ball or cop, whichis difficult if notimpossible to accomplish Where the winding-spindlebodily recedes in the arc of a circle or in a circular path, as hasheretofore been proposed. Further, by preserving the centers of theWinding-spindle and the thread-eye in the thread-guide coincident With ahorizontal line taken through the centers of such eye and spindle I amable to Wind any desired size of ball or cop, due to the fact that inthe motions of the sliding carriage or frame the spindle neverapproaches any part of the machine beneath such spindle and carriage, asis the case Where a windingspindle moves in the arc of a circle or in acircular path. In machines having a Winding-spindle which recedes in thearc of a circle from a reciprocatingthread-guide the spindle as itrecedes approaches a part or parts of the machine-frame beneath thespindle, and consequently the size of the ball or cop which can be Woundon aparticular machine is limited. This is objectionable and is avoidedby my invention in that balls or cops of much larger diameter or sizecan be Wound on the one machine, as there is ample room or space forthis purpose.

Another advantage resulting from the carriage or frame sliding in aright line horizontally resides in the fact that the carriage alwaysmoves in a steady manner and does not absolutely necessitate theemployment'of a counterbalancing-Weight,and,further,bounc ing orvibrating motions of the Winding-spindle or of the ball or cop beingWound are avoided,which bouncing or vibrating motions are incident tothose machines wherein the spindle recedes in the arc of a circle, dueto the fact that the carrier of the spindle is not steadily supportedand guided in a firm and substantial manner, as is the case with myIirmly-supported and accurately-guided carriage or frame, on which theWinding-spindle is mounted. Vhere a Winding-spindle recedesin the arc ofa circle, it is essential to employ a counterbalancing-Weight, becauseif the ball or cop is rough there will be a tendency for it to bounce orvibrate. By my horizontal sliding carriage, firmly supported andaccurately guided in a right line, I am able to Wind the ball or copaccurately and uniformly from end to end and can Wind large or smallballs or cops Without altering or changing the size, length, or heightof the thread-guide. The carriage or frame moving according to myinvention is not subject to jumping or Vibrating movements, and thismaterially contributes to obtaining perfect Winding. In my constructionit is possible to push the sliding carriage or frame and theWinding-spindle to the limit of its motion back of the trip-block, sothat the winding operation can be commenced While the Winding-spindleand its carriage are pushed to the rear side of the machine, therebyaffording every convenience and facility for properly placing the cordor thread in engagement with the thread-eye in the threadguide, whichcannot be conveniently effected when the winding operation is takingplace with the Winding-spindle or the ball or cop being Wound bearingagainst or in close proximity to the thread-guide itself.

A further advantage resulting from this construction of sliding carriageresides in the fact that I am thereby enabled to prevent danger of thethread being pushed od of the end of the cop and Wound upon the spindleon first starting the machine. This is liable to occur more especiallywhen the spindle has been stopped, the cop not being of the full orrequired size and it is desirable to wind on more thread. Under thesecircumstances it frequently occurs that When the thread-carrier isoscillating'rapidly against the surface of the revolving spool thethread-carrier does not take up the thread into the notch, but pushes itto one side. If the thread-carrier be right against the su rface of thecop, it then forces the thread of the cop onto the revolving hub of thespindle and cannot pick it up and the spindle will Wind the thread aboutitself and cause much Waste. When the thread-carrier is running againstthe surface of the cop, it necessarily forces the thread to traverse thefull length of the cop, which is of course the full length of thetraverse of the thread-guide, and if the thread does not lie in the eyeor notch of the thread-guide at the center thereof,but instead slipsdown to one side of the thread-carrier, it Will clearly be seen that thethread will be carried beyond the end of the cop, as above stated. Itwill be apparent, however, that if the thread-carrier is some distancefrom the cop it will not force the thread to traverse so far right andleft on the cop as the carrier itself goes, and the farther away thethread-carrier is from the spindle the shorter will be the traverse ofthe thread on the cop as compared with the actual traverse of thethread-carrier. Thus if the clutch mechanism should be operated to istart the spindle in the position of the parts- IOO IIO

IZO

shown in Fig. 1 audthe thread should not be in the eye of thethread-guide it will be seen that the thread will not wind to theextreme ends of the cop-tube, and hence the thread could not slip offand be wound upon the spindle and in a few traverses of the thread-guideit would take up the thread in its notch, which it could not do if thethread ,were being wound about the spindle. In other words, when thecarrier works against the surface of the cop the thread is forced totravel practically so far on the cop as the thread-carrier, no matterwhat be the speed or take-up of the spindle; but when the thread-carrieris reciprocating at a distance from the spindle the traverse on the copdepends upon the speed or take-up of the spindle, and no matter how fastthe spindle runs the thread-carrier must and will run ahead of or leadthe traverse of the thread on the ccp. Consequently under allcircumstances it is desirable to start the spindle when it is at itsgreatest distance from the moving thread-carrier, so as to avoid thepossibility of pushing the thread olf the end of the cop and letting itwrap about the spindle-hub. As soon as the thread `falls into the notchof the carrier the spindle and carrier may then be brought together.
